MACHINE FOR MAKING BOXES.

SPECIFICATION forming part of Letters Patent No. 393,404, dated November 27, 1888.

Application filed July 17, 1986.

To all whom it may concern.-

Be it known that I, JOHN RANDOLPH SToUT, of Brooklyn, county of Kings, and State of New York, have invented certain new and use ful Improvements in Machines for Making Boxes, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

The object of this invention is to provide an improved machine for making boxes from cardboard and the like.

The invention consists in the peculiar combinations and the construction, arrangement, and adaptation of parts, all as more fully hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming part of the specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a plan of the mold or female die. Fig. 2 is an end elevation of the same. Fig. 3 is an elevation showing the inner face of a portion of an end of the mold or female die. Fig. Tris a perspective View of the plunger or male (1e.

In the drawings, A represents the mold or female die, of which the sides, as shown, are formed of flanged dimension-pieces an, which may readily be removed and have others of different widths substituted for them in order to make the die shorter or longer,according to the dimensions of the box to be made. Each end of this mold or die A is composed of two plates, 7) 1), down through the upper edge of each of which a curved slot, 0, is made, and on the inner face of each plate b,beneath the lower margin of the slot 0, the plate is cut away, as shown in Fig. 3, so as to present asunken face within perpendicular linesff, fashioned into aconchoidalshell-likecurve,g,whiehellects the proper bending and lapping of the end or side lapping pieces of the box top and bottom.

Ordinarily a dimension or distance plate, 71, is fixed between the plates b b at each end, as shown in the drawings,and said plates or pieces Ir h may be of any desired width, according to the desired width of the box to be made. The inner or adjacent edges of these slotted plates D Z) and the distance-plate h (if there be one used between them) are projected somewhat Serial No.20S,f25S. fMorlcl.)

above the edge of the sill and together .form a high section, or, central between said slots 0, so that when a blank for forming a box top or bottom is pressed down into the female die the ends of the blank first coming in contact with these sections may be turned up before the lapping pieces of the box are bentinward in place.

All the parts of the female die have outside flanges, and are held together with belts 7c 7;, or other suitable devices.

Each plate I) has an opening, Z, below the curve {1, through which a straight roll, in, set on a suitably journaled shaft, m, projects slightly inward for the purpose of exerting a rolling pressure on the lapping pieces of the box tops and bottoms to press them in place as said topsand bottomsare formed and forced down through the mold A by the plunger or male die B. These rolls m may beset inward to apply greater pressure to the said lapping pieces or be adjusted to apply less pressure by turning the set-screws 00 one way or the other, as the case may be, as the bearings m of the shafts m are large enough to permit of such adjustment, and the setscrcws 0 0 bear upon said shafts,orsuch adj ustmentmay be desirable in reference to the thickness of the card-board of which the boxes are made.

The plunger or male die B, Fig. 4, is formed of flanged right-angled end pieces, pp, and dimension or distance pieces (1 q, flanged on the inside and held together by bolts 5, as shown. This die B,also,can be made of any desired dimensions by substituting wider or narrower pieces (1 for those shown in the same manner the female die may be changed.

The slotted plates 2) b of the female die may be constructed with right-angled offsets, so as to form complete cornerpieces of the die.

A box top or bottom blank of the form substantially as shown in my United States Patent No. 342,473,0f May 25, 1886, being placed 'on the top of the female die A, the male die is applied to force said blank down into said female die. This action causes the end and side rims of the blank to turn up as desired, and as the blank is forced farther down, the lapping pieces engage in the slots 0 c, and are by the shape thereof and by the peculiar conformation of the curves 9 bent in and lapped upon and to the-same extent as the dimensions of ICO the end or side rims as above, as the case may be. Then the continued movement of the plunger B forces the said blank farther down to the rolls m, which exert the desired pressure upon the said lapping pieces, and the further action of the plunger pushes the box cover or top out through the open bottom of the die A.

I do not confine myself to the special construction herein shown of the dimension or distance pieces, as it is evidentthat they may be made withoutflanges and may beheld together by other devices than the bolts shown.

The parts of the dies may be assembled in various ways; but in all cases the female die must have plane inner faces, excepting the slotted plates, and the male die plane outside faces.

Having thus described my in \'ention,I claim as new and desire to secure by Letters Patent- 1. In a machine for making boxes, a mold or female die formed of a plurality of plates with interchangeable distance or dimension plates, each removably secured directly to the adjacent plate, whereby the length of said die may be changed without changing the width, and vice versa, substantially as described.

2. In a machine for making boxes, a die formed of flanged plates,combined with flanged distance-plates and means for removably connecting the same, substantially as and for the purpose specified.

3. In a machine for making boxes.a mold or female die formed at its upper edge with curved slots,the acting edges of which begin flush with the side of the die at right angles to that side of the die in which the slot is formed, substantially as and for the purpose specified.

4. In a machine for making boxes, the combination,with a female die, A, constructed and arranged substantially as herein shown and described, of a male die, B, composed of several plates and made adjustable in length without changing the width, and vice versa, substantially as set forth.

5. In a box-making machine ofthe character substantially as herein specified, the combination,with a female die having the curved slots and the conehoidal recesses for bending the box lapping pieces into place, of a die-section central between said slots constructed to extend above the general edge of the die, substantially as herein shown and described, whereby in the operation of the machine the ends of the box may be turned up before the lapping pieces are bent inward, as set forth.

6. In a machine for making boxcs,amold or femaledie having each end composed (or partly composed) of two plates, I) b, each of which has a curved slot, 0, extending down through its upper edge, and has also in its inner face, beneath the lower margin of the slot c,a sunken face fashioned into a conehoidal shell; like curve, 9, the inner or adjacent edges of said plates being projected somewhat above the dieedge, all arranged substantially as and for the purposes set forth.

In testimony that I claim the foregoing I have hereunto set my hand in the presence of two witnesses.

JOHN R. STOUT.
